During the summer, your AC provides unparalleled relief from the heat of St. Louis, Missouri. But that relief is hampered when you hear your AC kick in and you quickly get slammed with an awful odor. Not only are these smells unpleasant and distracting, but they could also indicate more significant issues with your HVAC system and the overall health of your home. By identifying the sources of odors coming from your AC vents, you can act quickly to contain the problem before it gets out of control.

What’s That Smell?

Before you go any further, be sure that the odor you’re catching isn’t coming from somewhere else in your home, such as from a trash can or through an open window. Once you’re sure that the smells are coming from your AC vents, you’re ready to go odor-hunting.

Different odors usually point toward different potential issues. A musty smell, for example, generally indicates mold or mildew growth somewhere in your HVAC system. Mold spores can grow on your system’s condenser coil if there is some kind of drainage or ventilation issue. Spores can also seep in through leaks in your duct system and lay down their roots there.

On the other hand, a stench like rotten eggs could indicate a natural gas leak, which you should act on immediately. A burning smell should also be acted upon quickly, since it could mean there’s a mechanical problem in your system.

What Can I Do?

Don’t just spray air freshener to try and eliminate these stenches. You can reduce some HVAC odors by regularly replacing your HVAC system’s air filter, but most of the measures necessary to quell these odors should be taken by your local HVAC contractor. In order to solve the problem, they may have to repair or replace a component of your system. They can also check for leaks in your ducts where mold may be growing.
